Dear:
I am writing to express my sincere apology for failing to keep my promise. I won't be able to go to Beijing with you as scheduled because I injured my foot when I played basketball last night.
Due to my severe injury, I have to stay at home for at least two weeks, which makes it impossible for me to join you. I'm not writing to cancel our plan but postpone it if possible. Would it be convenient for you if we go to Beijing next month? I hope the change will not cause you too much trouble.
Sorry again for the inconvenience, and I am looking forward to your reply.
yours′
